Epic Web Services (EWS) is the core integration layer of the Epic Systems platform, designed to facilitate seamless data exchange between the Epic Electronic Health Record (EHR) and third-party applications and systems. Available through the open.epic developer portal, EWS offers a comprehensive set of APIs and specifications that allow developers to build connected applications for various healthcare workflows. The services are purpose-built to address integration needs where standard protocols may be insufficient or overly complex. Key capabilities include:
- Interoperability: Facilitating the exchange of patient records with non-Epic organizations and supporting federal frameworks like TEFCA.
- Workflow Integration: Services for outbound faxing, print job management, document linking (e.g., to claims), and phone system pause/resume during credit card payments.
- Core Data Access: APIs for essential functions like Patient Lookup, Identifiers, and Personnel Management (creating/updating user records).
- Developer Support: Access to over 750 no-cost APIs and interfaces, with sandbox access and support available through Vendor Services.
Epic EWS targets third-party software vendors, health system IT teams, and app developers looking to integrate their products (e.g., medical devices, lab systems, coding systems, patient-facing apps) directly into the Epic ecosystem.
